Implementation

Future<int> update(Map<String, dynamic> value) async {
  _setStatement(Operator.update);
  _setColumns(value.keys.toList());
  _values = value.values.join(', ');
  value.forEach((String k, dynamic v) {
    if (_set == '') {
      _set = '$k = $v';
      if (v is String) {
        _set = "$k = '$v'";
      }
    } else {
      _set = '$_set, $k = $v';
      if (v is String) {
        _set = "$_set, $k = '$v'";
      }

  _buildSql();
  var affectedRows = await db.update(_sql);
